Former British pop star SINITTA has applied to adopt two British children after she lost twins through a surrogate mother. The SO MACHO singer, whose ex-boyfriends include American Idol judge Simon Cowell and Brad Pitt, is hoping to provide a home for a mixed-race young brother and sister with husband of four years ANDY WILLNER. She says, "There are literally hundreds of mixed-race babies in children's homes but it's difficult to find parents for them."
